  <h2 id="masterplan">Masterplan</h2>
  <p>Stage 1: very safe</p>
  <ul>
  <li>Close all ports</li>
  <li>Nuke (or stop) all old VMs (exclude OPNSense)</li>
  <li>Make DMZ</li>
  <li>Make new basic VMs (cloning deb12 template)</li>
  <li>Open basic ports</li>
  </ul>
  <p>Stage 2: new services</p>
  <ul>
  <li>IONOS VPS for mail</li>
  <li>Some new very safe services</li>
  <li>HE IPv6 tunnel</li>
  <li>Own authoritative nameservers for domain zone</li>
  </ul>
  <p>Stage 3*: finally</p>
  <ul>
  <li>Another VPS in unknown provider for
  <ul>
  <li>Tor</li>
  <li>Reverse-proxying the media library</li>
  </ul></li>
  <li>PHP on main site with more web services from scratch, hopefully
  secure</li>
  <li>More new services</li>
